[mrtg] kMG confusion :(

[John Navarro]

My graphs show a maximum value to 1280.0k for my gigabit ethernet. How
can I make it show 128.0m instead? My maxbyes is set correclty. I
can't figure out the kMG line - how frustrating.

Thanks,
John

You should probably not use a kMG line at all.

If you have the correct maxbytes setting and use the Unscaled
option, the graph should scale to its maximum.

cheers,

Actually, the problem is that SNMP V1 32 bit counters roll over at about
128mb/s with a five minute sample. change to snmp V2c 64 bit counters and
remove all of the kMG stuff and it will work fine.

e.g:
target[router-ge0-0] #ge0/0:***@172.16.0.1:::::2
